CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Ethylphenol is a yellow liquid. Freezing point -18 °C. Flash point 172 °F. |
|---|---|
| Color/Form | METASTABLE & STABLE CRYSTAL FORM |
| Odor | Phenol odor |
| Boiling Point | 400.14 °F at 760 mmHg (NTP, 1992) |
| Melting Point | -18 °F (NTP, 1992) |
| Flash Point | 173 °F (NTP, 1992) |
| Solubility | less than 1 mg/mL at 72 °F (NTP, 1992) |
| Density | 1.037 (USCG, 1999) - Denser than water; will sink |
| Vapor Pressure | 1 mmHg at 115.2 °F ; 5 mmHg at 164.1 °F; 10 mmHg at 188.6 °F (NTP, 1992) |
| LogP | Log Kow = 2.47 |
| Stability/Shelf Life | COOLING LIQUID TO -30 °C GIVES METASTABLE CRYSTAL FORM, WHEN KEPT FOR 24-48 HR, THIS CHANGES TO STABLE CRYSTAL FORM |
| Refractive Index | MAX ABSORPTION (CYCLOHEXANE): 270 NM (LOG E= 3.30), 276 NM (LOG E= 3.28); INDEX OF REFRACTION: 1.5367 @ 20 °C/D |
| Dissociation Constants | pK = 10.2 |
| Kovats Retention Index | 1112.8 1108 1110 1106 1112 1112 1113 1115 1118 1104 1110 1114 1115 1113 1145 1115 1113 1119.7 1111 1177 |
| Other Experimental Properties | Cooling the liquid to -30 °C gives a metastable cryst form, mp about -28 °C; when kept for 24-48 hrs, this changes to the stable cryst form, mp -3.4 °C. |
